David Healy is keen to make sure he does not slip out of the Northern Ireland picture by playing more first-team football for Sunderland.
Northern Ireland manager Nigel Worthington recently stated it would boost the nation if more of his squad were regulars at club level.
The country's all-time leading scorer Healy falls into that bracket having made just three Premier League appearances this season.
Healy has met with manager Roy Keane over his future and now the ex-Fulham and Leeds striker is looking to get his head down in order to force his way into the Irishman's plans.
"It's disappointing," he told Sky Sports News, on his lack of first-team football for Sunderland.
"I'm sure that any player in any league will tell you that when you're not playing it's disappointing.
"I've spoken to the manager about it and it's something that I've got to understand.
"I'll get my head down and get on with it and work day in and day out in training or the reserves."
Meanwhile, Healy stands by his previous comments that Manchester United defender Jonny Evans could go on to win over 100 caps for Northern Ireland.
"When he first came on the scene I said 'Jonny Evans could be one to go on and break the 100 cap barrier' and I stand by that," he continued.
"He's got everything. People forget how young he is and how mature as a player he is and how good he is going to be in the years to come."
